Ethereum Funding Crunch Risks Delaying 2026 Upgrades
Glamsterdam upgrade enters final devnet phase targeting H2 2026 activation CIP funding expires April 2026 creating 3-9 month shortfall window for $30M core
Summary
- Glamsterdam upgrade enters final devnet phase targeting H2 2026 activation
- CIP funding expires April 2026 creating 3-9 month shortfall window for $30M core dev needs
- No alternative funding mechanism identified as treasury pressures mount
Ethereum core devs face an imminent funding shortfall. It could stall the Glamsterdam upgrade now set for the second half of 2026. The Community Improvement Proposal funding model ends in April 2026. It supplies the roughly $30 million needed each year for client teams and protocol work.
Without a confirmed replacement, the gap opens within three to nine months.
This risk arrives at a critical moment. Glamsterdam has already reached its final devnet stage with all planned EIPs active.
Context
Ethereum's upgrade path depends on steady support for client teams. These teams maintain and improve the protocol. The four-year Client Incentive Program under CIP has sent staking-derived funds to them since launch.
The program expires in April 2026. No successor model is secured yet.
Glamsterdam targets a 200 million gas limit and 10,000 transactions per second. The upgrade stays on schedule through current devnet testing. Core contributors have flagged that the loss of CIP support could interrupt that work.
Details
Analyses of treasury flows and program expirations have issued the warning. Reports show spending pressure on Ethereum treasuries already by mid-2026. Core development needs about $30 million each year. That figure ties directly to the CIP model ending next April.
"The expiration of the current Community Improvement Proposal funding model could lead to a funding crisis within the next three to nine months."

No replacement mechanism has been confirmed. Glamsterdam continues through its final devnet phase with every EIP activated. The absence of new funding sources leaves the 2026 timeline exposed once CIP ends.
Outlook
Developers shift focus to testnet deployments for Glamsterdam. The ecosystem hunts for new funding structures at the same time.
The next three to nine months will decide if core protocol work continues without a hitch toward H2 2026 activation.
